Bug fixes and cleanups around exit_validator 
Cleanups

* Use `state.slot` over `current_slot`.
* Specify `new_status`
* Segregate ejection processing

Bug fixes:

* Put ejections at the end of the per-slot processing (TODO: per-slot processing should come *after* per-epoch processing)
* Immediately exit ejections
* Include `ACTIVE_PENDING_EXIT` as an active state
* Renamed two `State` to `BeaconState`

Move to a per-slot state transition function 
Initial pass for the migration from a per-block state transition function to a per-slot state transition function. More simplifications and cleanups can be made.

Handle activations and exits separately for balance churn (#230) 
This change is to avoid deposits from fully consuming the allowable balance churn, preventing exits from being processed. And vice versa with deposits/exits swapped.

A bunch of cleanups and bug fixes were made along the way.

Cleanups pt. 1 (#185) 
Many cleanups in this monster commit! Two warnings:

1) More significant cleanups will be coming soon™.
2) While several bugs were fixed in this cleanup, some will undoubtedly have been introduced (thanks to the three reviewers!). In particular, the logic around validator statuses is known to be broken.

* If B3 is justified using source B1, and B1 has been justified, then B1 is finalized.

* Add shard blocks, shard data roots and how data is computed into crosslinks

Includes:

* Shard block structure
* Shard block header verification rule
* Shard block fork choice rule
* Shard block body verification rule
* Crosslink verification rule

Possible simplification: require `calc_block_maxbytes` to always output an exact power of two; if we desire the average maxbytes to be smooth, we can simply make it a pseudorandom chose between powers. This reduces some of the padding complexity.

Fixed bug in previous version 
Validators cannot simply be "popped out" of the list because it's super-important for validator indices to be immutable.

Instead, the validator stays until a new run of `add_validator` swaps it out.

* Making data structure names consistent (e.g. `SpecialObject` => `SpecialRecord`)
* Arranging the fields within the data structures in a more logical/consistent manner
* Reworking the comments to be more concise and to the point
* Rename some fields for consistency:
    * `shard_id` => `shard` (for consistency with `withdrawal_shard`)
    * `last_state_recalculation` => `last_state_recalculation_slot` (for consistency with `last_finalized_slot`, `last_justified_slot`, etc.)
    * `current_dynasty` => `dynasty` (for consistency with `slot`, `shard`)
    * `pow_chain_ref` => `pow_chain_reference` (abbreviations are avoided throughout)
* Various other cleanups
